“ ANALYSIS OF WAFFLE SLABS WITH OPENINGS”of the first problem. DDM will be employed to solve such stress disturbanceproblems. Iteration will be performed between the external boundaries of theplate and the crack faces until all boundary conditions are satisfied.The obtained results compared with the previous analytical one. Further, aanalysis study is introduced to investigate the effect of elastic and geometriccharacteristics of the cracked plate, on the values of stress intensity factor
